Hosting Phone Books on a PBS Server

You do not need to run PBS on a high-end computer because any computer capable of running Windows Server 2003 and Internet Information Services (IIS) can run PBS.

Just before publishing, ensure that the PBS server is using IIS to run FTP and the Web server service. This is necessary for PBS servers to receive posts from PBA and to provide updated files to clients. For more information about IIS, "Internet Information Services (IIS) 6.0 overview" in Help and Support Center for Windows Server 2003.

Caution

For security reasons, do not allow anonymous FTP access to your PBS server. Also, only run the FTP service when you are actually publishing or updating a phone book. For more information about CPS security, see "Security information for Connection Point Services" in Help and Support Center for Windows Server 2003.

PBS servers can be located on your perimeter network or in the perimeter network of the ISP if you outsource phone book support. Because the phone book updates after connecting to your network, locate the PBS server such that the client has access to it after a successful connection to your network. For more information about security in perimeter networks, see "Securing Network Perimeters with ISA Server in this book.
